does anybody know of any other company that makes a good performance intake manifold for tpi other then tpis. there to expensive for me

 

I think Edelbrock makes one, but its probably just as expensive. Check with SLP they might produce one

 

I am happy with my Accel Superram one.

 

Holley, Stealth Ram, but you'll need a different or modified fuel rail. About $290 for the intake, $150 for the fuel rails, depending on where you shop. They claim high HP gains on stock motors.

 

TPIS, Accel, Edelbrock, F.A.S.T. looking around $360 - $450
Arizona Speed and Marine, Street & Performance has some as well.

 

Visit Thunder Racing website. You can purchase the complete plenum/manifold and fuel rails with adjustable fuel press regulator for $500. I installed one recently and the pulling and breathing power of the setup are fantastic. You can actually feel the difference in the seat of your pants........

 

I'll be going with the stealth ram on my 88 Formula. Looks like the best bang for the buck. a few of my friends are going to get it as well.
